Most chains do not allow swapping points, or if there is a way, it's a horrid exchange rate (say, via points.com).

Try to concentrate your hotel points in as few places, as possible. If you have to stay at other places, try to do it in your 2nd choice preferred place.

Some chains offer status matches, or a challenge. I know Hyatt's was 12 nights in 90 days. Plus you got 4 suite upgrades upon signing up for it.

Perhaps Hilton has something similar. I was Hilton diamond for a couple of years. The promos dried up though, so I departed for greener pastures. Now the same thing has happened at Hyatt, but the suite upgrades, and other perks kept me around. I just dropped one level a month ago, so will have to see how mortals live.

Priority Club (Holiday Inn, Crowne Plaza, etc) has lots of promos, and has lots of properties.
